A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawings, in which:

Fig. 1 isa perspective View of my improved hose clamp, an applying toolin operative relation thereto being indicated by dotted lines. e

Fig. 2 is a fragmentary longitudinal section of my improved hoseconnection or coupling in section on line 2-2 of Fig. 3. Fig. 3 is atransverse section on line 3--3 of Figs. 1 and 2.

Fig. 4 is a plan view of the coupling extended or flattened.`

In the accompanying drawings 1 represents va coupling member and 2 ahose. My improved hose clamp is formed integrally of sheet metal andconsists of a band portion 3- having a longitudinal rib 4 struck outtherefrom and a head portion 5 having a loop-like keeper 6 adapted toreceive the end of the band. This'keeperis struck up centrally fromthejhead.

The rib at the end portion .of the band has a pluraltv of indentationsformed therein providing lratchet teeth 7, lwhile the keeper has aplurality of indentations formed therein providing the teeth 8coactingwith the teeth 7 of the band, so that when the band is insertedwithin the keeper the teeth on the 40 head and .band engage and provideavery secureconnection for-the band to the head.
